Gibson made a similar product during their tweed era, around 1960. It was a reverb amp with no drive circuit, just a return circuit with a power amp and small speaker. The input was a zip cord with two alligator clips, and derived the spring drive signal directly from the speaker of another amp (through a 47 ohm dropping resistor). It did have a 1/4" input to allow you to use it as a small amplifier as well.

Thanks, again.

  I had to dig to find that one. It was a GA-1RT-1. It was basically the 1961 GA-5 circuit (after they changed to 6BM8 power tube). Note that it also has 1/4 inputs to allow use as a normal amp, but if you used them, there was no reverb because there was no drive circuit.

    Most excellent! How did this unit's tonal range compare to Fender's 6G15?
    
    Much thanks! Have a good one.

      Not nearly as rich sounding as Fender's reverb. Also, not as clean. This circuit has more gain than Fender's, and can be overdriven easily. AFAIK, this was the first commercially available outboard reverb unit.

        Best stand-alone Reverb/Delay unit I've used. Works well with nearly all amp types. Great information on that Gibson unit. Gonna have to look for one.
